The problem with that list is that most of it is very difficult to get hold of! Trust me I have tried! (especially on a tight budget like mine)

There is no such thing as too much knowlege, excuse the cliche, but knowlege is power. So to answer your question, no amount of reading and research is enough!

Throughout history it has been the inaction of those who could have acted, the indifference of those who should have known better, the silence of the voice of justice when it mattered most,that has made it possible for evil to triumph.HIM
